Silver - Cadmium - Indium

Introduction

The solubility limit of Cd and In in the (Ag)-phase, α, was studied at 315°C and at room temperature by X-ray diffraction and metallography on 33 samples. The samples were melted from the elements, homogenized, and slowly cooled to room temperature or quenched from 315°C [67Sny]. In the two-phase samples, the second phase was identified as having a close packed hexagonal cell that occurs in both the Ag-In and Ag-Cd edge binary systems at 315°C, denoted by ζ. From this and the metallographic similarity it is likely that ζ forms a band of solid solutions in the ternary. The experimental method is given in more detail in the original thesis work [61Sny], where nine additional alloys are discussed and resistivity and dilatometry measurements are reported, especially on the low-indium side (< 3 mass% In) of...
